Abstract: A hydraulic connector arrangement includes a shaft member, a banjo fitting, a pair of sealing members and a banjo fixing member. The shaft member has a hydraulic passageway and an opening that extends from the hydraulic passageway to an outer surface of the shaft member. The banjo fitting rotatably extends around the shaft member covering the opening. The pair of sealing members are disposed between the shaft member and the banjo member and on opposite sides of the opening. The banjo fixing member is coupled to the shaft member to retain the banjo fitting to the shaft member. Further, the banjo fixing member is dimensioned to allow rotation of the banjo relative to the shaft member and the banjo fixing member.

Abstract: There is provided a turbo blower for lasers which is capable of effectively cooling a shaft and bearings thereof. Oil held in a shaft support member is drawn up via an oil inlet port by a centrifugal force generated by rotation of the shaft, and passes through a cooling oil passage extending through the shaft to be discharged from an oil outlet port provided below an upper one of rolling bearings as the bearings. The oil discharged from the outlet port returns via an oil return passage to an oil sump. While passing through the oil return passage, the oil is cooled by a coolant circulating through an coolant passage. Further, part of the oil discharged from the oil outlet port is supplied to the upper one of the bearings for lubrication. On the other hand, part of the oil held within the shaft support member is drawn up along a tapered portion of an oil suction head by the centrifugal force generated by rotation of the oil suction head for lubrication of a corresponding one of the rolling bearings. A large amount of oil flowing through the cooling oil passage can deprive the shaft and the rotor of heat, thereby effectively cooling the bearings as well.

Abstract: A synchronization control circuit applicable to a TDMA (Time Division Multiple Access) digital mobile communication system for controlling the transmission and reception time base of a mobile station on which the circuit is mounted. The synchronization control circuit includes a plurality of time base counter circuits each counting down standard clock pulses to generate a plurality of timing pulse sequences having time bases which are respectively associated with the cells of the system. All the time base counter circuits share a single counter controller which controls the writing and reading of counts out of the time base counter circuits. The counter controller selectively produces the outputs of one of the time base counter circuits as a timing pulse sequence. The synchronization control circuit, therefore, is small size and light weight and saves power.

Abstract: In a TDMA cellular mobile communications system, a mobile station receives a TDM signal from a cell site and detects a sync, a timeslot assignment signal and a signal indicating the propagation delay time of signals between the cell site and the mobile station. From an assigned timeslot, a time interval from a detected frame sync to the time of transmission of a burst signal from the mobile station is determined. The propagation delay time indicated by the detected signal is subtracted from the determined time interval. When a frame sync is detected from the received TDM signal, clock pulses are counted until it corresponds to the subtracted time interval, whereupon a timing pulse is generated to cause a burst signal to be transmitted from the mobile station to the cell site.
